This may not be all that helpful but LTSpice can output waveforms to
WAV format. If you can make a circuit to generate the waveform, or if
you can combine a bunch of the built-in signal generation options
(e.g., sine waves, pulses, look-up tables, math functions, etc.) to
get the waveform you want, you can output it to a WAV. Also, it can
take WAV input, so you can, say, implement a circuit which filters or
distorts a signal, feed it an existing WAV, and then save the output
to WAV. It can read/write a wide range of sample rates and bit depths,
too, so you can, if you want, make a 1 megasample/sec WAV, for
example.
